About HIV-1 protease

HIV-1 protease is an essential retroviral aspartyl protease required for HIV replication. It cleaves viral precursor polyproteins into functional proteins, enabling viral assembly and infectivity. Inhibiting HIV-1 protease prevents the maturation of new viral particles, halting further infection.

How We Calculate These Metrics

Target Attractiveness Score

A 0-100 score based on trial activity, sponsor diversity, and completion rates. Calculated from 63 clinical trials targeting HIV-1 protease.

Completion rate: Percentage of trials that reached their planned endpoint. Trials terminated early, withdrawn, or suspended are not counted—these often indicate safety issues, lack of efficacy, or strategic pivots.

  • Highly Attractive (80+): High trial activity, many sponsors, strong completion rates
  • Attractive (60-79): Good trial activity and validation
  • Moderate (40-59): Moderate interest from sponsors
  • Low (under 40): Limited trial activity or validation concerns

Strategic Insights

Auto-generated insights based on trial analytics including competition intensity, white space opportunities, modality shifts, and failure patterns. We analyze trial sponsors, phases, indications, and outcomes.

Risk Signals

  • High Competition: Many sponsors competing for this target (may reduce market opportunity)
  • High Failure Risk: Low trial completion rates suggest development challenges
  • Low Validation: Limited trial activity or poor outcomes indicate uncertain viability
  • White Space Available: Underexplored indications present opportunities
